At this time, no one dared to speak, and their hearts were pounding.

They looked at His Majesty with their spare eyes, only to see Li Shimin's face full of iron, and he trembled with anger.

Qin Shou was holding his head up at the moment, with a relaxed face.

He smiled and comforted Li Shimin: "Don't worry, father-in-law, you put a hundred hearts, even if Li's second daughter takes a fancy to us and cries and shouts to let us be horses, then I would rather die." ”

"This heart, this will, this feeling, heaven and earth are proof, and the sun and the moon can be learned."

"Besides, father-in-law, you really don't have to say anything to me, open-mindedness is like a light in the sky, illuminating my life......"

Qin Shou stretched out his hand, his face full of firmness and composure.

At this time, of course, he knew what he had to do!

It's not wrong to be faithful.

The most important thing is that I really don't want to change my father-in-law!

"......" Everyone looked at Qin Shou stunned, their eyes full of strangeness.

Especially Li Chengqian, Li Tai and other princes, the corners of their mouths kept twitching.

Why do you have the face to say this?

Who is the connotation?

"Humph!"

Li Shimin's face turned purple and he took a few deep breaths and suppressed the anger in his heart.

With such a mix, Li Shimin's eagerness to reveal his identity was suddenly diluted a lot.

He really didn't expect him to be so jealous of the royal family?

In addition, Li Shimin is also hesitating about how the two sides should get along once their identities are revealed?

"Forget it, let's not talk about it." Li Shimin sighed, turned his eyes like torches and stared at Qin Shou and asked: You still tell me about this rice seed. ”

"What's the matter....... Suddenly the output has increased? ”

"What the hell is going on?"

The treasury needs taxes, and the war needs money.

Which industry do you expect people to contribute? Not agriculture yet?

Because this is the most stable industry.

As for the handicraft industry, the handicraft industry and agriculture at this time were inseparable.

Is it commercial? Merchants are engaged in business and selling, running around, so that how much money can be made after the collection of taxes?

Therefore, as a ruler, Li Shimin attaches more importance to agriculture than the emperors in the past, and implements the system of equalizing land, rewarding land reclamation, lightly dispensing with small endowments, and persuading farmers to teach mulberry, which does not violate the agricultural time...... The implementation of a series of policies that value the people is aimed at developing agriculture.

But all of this is not as good as this "600 catties per mu", it can be said that when he heard the news, he was simply stunned.

I'll talk about the identity issue later, but the food issue, that must be clarified no matter what.

If it can really be promoted in large quantities, won't the hungry days of the people of the Tang Dynasty be solved? Won't Datang's treasury and grain depot be filled?

Looking at his father-in-law's eager gaze, Qin Shou couldn't help but hold his forehead, his head was big.

Asked again?

Others, including his uncle, could refuse to answer, but when his father-in-law asked this, he had to say a few words.

At this time, the eldest grandson Wuji, Li Chengqian, Li Tai and others couldn't help but turn their heads to look at Qin Shou, their eyes were full of light, obviously they were not happy with the previous question.

Qin Shou looked at everyone, he was speechless, he was really convinced to have this kind of relative!

He pulled his hair and said helplessly: "To put it simply, this is called hybridization, which is a classic and commonly used method in breeding.

"It's a way to get some of the good genes of both parents by combining two different individuals."

Nima!

Say bald mouth again!

Seeing that everyone frowned, Qin Shou hurriedly waved his hand and explained, "What's that...... You don't have to pay attention to the genes, just understand them as their own merits. ”

"You just have to understand that, generally speaking, two different breeds together tend to allow future generations to inherit their respective advantages and create new and more advantageous breeds."

"The advantage of hybridization is that the crop has more seeds and higher yields; domestic animals have more litters and a high survival rate; There are also more advantages, such as hybrids have strong vitality, wide adaptability, strong vitality and competitiveness. ”

"For example, a sheep, one is hardy and has many cubs, and the other grows fast and produces more meat, so let these two different goats combine to create a sheep that is hardy, grows fast, has more cubs, and produces more meat."

Qin Shou didn't say much, because he knew that the more he talked, the more difficult it was to explain.

Even if Qin Shou only said a few words, Li Shimin frowned, and his eyes were full of doubt.

This concept was like a thunderstorm in the minds of Li Shimin and everyone present.

Especially the eldest grandson Wuji, Li Chengqian, and Li Tai.

If Qin Shou explained to them how to breed before, they were still confused, but now they fully understand.

Li Tai said faintly: "Isn't this just a mongrel?" ”

"Uh...... You're right! Qin Shou pursed his lips and nodded.

Everyone's faces suddenly became a little weird.

Do hybrids have an advantage?

Nima!

This statement is appalling!

All of a sudden, it subverted people's cognition.

Li Chengqian's face was full of excitement, "I....... I see, that's how the mules came to be? ”

"Ahem, cough, cough......" Qin Shou picked up his water cup and just took a sip, and when he heard the words, he coughed it all out at once, "Mule, it was an accident!" ”

"That's two races, with birth defects."

Li Shimin and the others also twitched on their faces......

Everyone couldn't help but be silent for a while, and suddenly Li Tai raised his head and asked weakly: "Then according to this, do people also have such characteristics?" ”

“？？”

The crowd looked up again.

Qin Shou was also stunned, and couldn't help scratching his head, he really hadn't thought about this issue before, but when Li Tai mentioned it like this, he suddenly felt that this matter was really hard to say.

Otherwise, why do they say that mixed-race children are generally more beautiful?

Perhaps this phenomenon can be explained by this.

Qin Shou looked at Li Tai with some admiration: "Fourth brother, you are the real talent!" Can you think of this? ”

"Don't say it, I think of a question that proves this statement from the opposite side, and you will understand as soon as I say it."

"Have you noticed that many close relatives who marry such as cousins have a much higher proportion of children with congenital disabilities or congenital diseases than those who marry from different clans?"

"Believe me, this man can't marry close relatives."

Yes?

Everyone was stunned when they heard this, their eyes flickered, and their scalps were numb.

The waves are tumbling in my heart.

In the past, I always felt that close relatives were married to each other, and it was not surprising that there were many congenital disabilities or congenital diseases among their children.

Unexpectedly, the problem is here?

The monarchs and ministers couldn't help but feel a chill down their spine, from the heel to the back of their head.

Nima, this is a big problem!

......

On the way back, everyone's minds were drowsy.

At the same time, several princes unconsciously looked at Qin Shou with a bit of respect.

On the way back, Qin Shou's house passed first, and it was already dark at this time, Qin Shou got out of the car and said to Li Shimin and the others: "Father-in-law, it's so late, come to the house for a light meal and then go back?" ”

"No, I still have something to do, so don't go in and disturb me." Li Shimin said lightly.

This made the eyes of several other people darken.

Li Chengqian: "Father, my leg is a little uncomfortable, and I want to rest at my brother-in-law's house for a while before leaving, do you think so?" ”

"Oh, does it matter?" Li Shimin knew that the prince had a leg disease, so he couldn't help but be concerned.

"It doesn't matter, you may be tired, just rest for a while!" Li Chengqian bowed his head and said.

"Hmm....." Li Shimin nodded in agreement.

The eldest grandson Wuji, Li Tai, and Li Zhi changed their faces wildly.

They also knew that the prince had a leg disease, but he didn't have a seizure when he ran to the suburbs today, but he had a seizure when he came back by car?

The devil only believes it!

The prince must have wanted to ask Qin Shou something.

But since His Majesty had already spoken, he had no excuse to find for his leg disease, so he could only watch Li Chengqian stay.

Watching the carriage leave, Li Chengqian's eyes flickered, and he turned his head to look at Qin Shou with a smile, "Brother-in-law, I'll bother you for a while, don't mind!" ”

"Where can I be, big brother, please come inside!"

Qin Shou didn't understand the situation, and really thought that the eldest brother's leg hurt, so he hurriedly stepped forward to help Li Chengqian.

And Li Chengqian quietly examined this "brother-in-law", from some previous rumors and what he had just experienced, he found that his brother-in-law was more and more shocking.

"Big brother, have a cup of tea first, eat here before leaving!" Qin Shou finished making tea and was about to beckon him to dinner.

Li Chengqian stopped Qin Shou, "Don't be busy, I'll leave after a while." ”

"Brother-in-law, we are not outsiders, I really think you are a person who does great things, haven't you ever thought about becoming a professional?"

Qin Shou couldn't help but be happy when he heard this, "Big brother, I won't tell you, how can I not think about it, but there is a saying, don't do porcelain work without diamonds, we have no way, and we have no status, you say ......"

"I can do this for you, brother-in-law, you say, which department do you want to enter?" Li Chengqian said seriously.

For Qin Shou, he can't talk about why, he has an intuition that if he doesn't hold it in his hands, I'm afraid it will become a big trouble.

What's more, I have seen the situation today.

Li Tai, Li Zhi, and the eldest grandson Wuji are all here, and their purpose is undoubted.

This made his heart suddenly increase a sense of crisis.

Therefore, he did not hesitate to lie and stay, just because he wanted to fight for his father's blame, and he also had to win some opportunities for himself.

"Huh?" Qin Shou's eyes widened suddenly, and he asked in surprise, "No, big brother, don't joke with me, is there really such a way?" ”

"Really!" Li Chengqian nodded.
